func (*DefaultErrorCollector) Result

func (inst *DefaultErrorCollector) Result() error

type Disposable

type Disposable interface {
	Dispose() error
}

Disposable 接口用于释放对象持有的资源

type ErrorCollector

type ErrorCollector interface {
	Append(err error)
	AppendIfFalse(ok bool, msg string)
	AppendIfNil(target Object, msg string)

	LastError() error
	Result() error
}

ErrorCollector 表示一个错误收集器
